Rehabilitation after Distal Radius Fractures: Opportunities for Improvement.

Background Exercises are frequently prescribed to regain function; yet there is no consensus on a standardized protocol, and adherence is low. Smart technology innovations, such as mobile applications, may be useful to provide home-based patient support in rehabilitation after distal radius fractures. Purposes Our purpose was to establish the potential of digital innovations for support and monitoring of patients and treatment adherence in rehabilitation programs, and additionally, to compare the current practice among physiotherapists to the various wrist exercise regimens and their effectiveness as described in the literature. Methods Standard practice, including the use of support tools for treatment adherence, was evaluated using a nationwide survey. Then, scientific databases were searched using "distal radius fracture" and "physiotherapy" or "exercise therapy," and related search terms, up until 23 March 2023. Results of the survey and literature review were compared. Results The survey was completed by 92 therapists. Nonstandardized support tools were used by 81.6% of respondents; 53.2% used some form of technology, including taking photos on the patients' smartphone for home reference. In the literature review, 23 studies were included, of which five described an exercise protocol. Treatment adherence was not reported in any of the included studies. Two studies described the use of smart technology or support tools. Conclusions There is no consensus on a standardized exercise protocol for rehabilitation after distal radius fractures, neither from a systematic literature search nor from a nationwide survey. Smart technology may facilitate monitoring of patients and exercise adherence, hereby supporting self-efficacy and improving adherence and outcomes.

Apps in healthcare and medical research; European legislation and practical tips every healthcare provider should know.

BACKGROUND: The use of apps in healthcare and medical research is increasing. Apps in healthcare may be beneficial to patients and healthcare professionals, but their use comes with potential risks. How to use apps in clinical care is not standard part of medical training, resulting in a lack of knowledge. As healthcare professionals and their employers can be held accountable for the wrongful use of medical apps, this situation is undesirable. This article addresses the most important European legislation regarding medical apps from the perspective of healthcare providers. METHODS: This review provides an overview of current and changing regulations, focusing on apps used in healthcare and medical research. Three topics are discussed: 1) the relevant European legislation and its enforcement, 2) the responsibilities and liability of the medical professional when using these apps, and 3) an overview of the most practical considerations medical professionals should know when using or building a medical app. RESULTS: When using and developing medical apps, data privacy must be guaranteed according to the GDPR guidelines. Several international standards make it easier to comply with the GDPR, such as ISO/IEC 27001 and 27002. Medical Devices Regulation was implemented on May 26, 2021, and as a result, medical apps will more often qualify as medical devices. The important guidelines for manufacturers to comply with Medical Devices Regulation are ISO 13485, ISO 17021, ISO 14971 and ISO/TS 82304-2. CONCLUSION: The use of medical apps in healthcare and medical research can be beneficial to patients, medical professionals, and society as a whole. This article provides background information on legislation and a comprehensive checklist for anyone wanting to start using or building medical apps.

Validity and reliability of a wearable-controlled serious game and goniometer for telemonitoring of wrist fracture rehabilitation.

PURPOSE: To determine the validity of wrist range of motion (ROM) measurements by the wearable-controlled ReValidate! wrist-rehabilitation game, which simultaneously acts as a digital goniometer. Furthermore, to establish the reliability of the game by contrasting ROM measurements to those found by medical experts using a universal goniometer. METHODS: As the universal goniometer is considered the reference standard, inter-rater reliability between surgeons was first determined. Internal validity of the game ROM measurements was determined in a test-retest setting with healthy volunteers. The reliability of the game was tested in 34 patients with a restricted range of motion, in whom the ROM was measured by experts as well as digitally. Intraclass-correlation coefficients (ICCs) were determined and outcomes were analyzed using Bland-Altman plots. RESULTS: Inter-rater reliability between experts using a universal goniometer was poor, with ICCs of 0.002, 0.160 and 0.520. Internal validity testing of the game found ICCs of - 0.693, 0.376 and 0.863, thus ranging from poor to good. Reliability testing of the game compared to medical expert measurements, found that mean differences were small for the flexion-extension arc and the radial deviation-ulnar deviation arc. CONCLUSION: The ReValidate! game is a reliable home-monitoring device digitally measuring ROM in the wrist. Interestingly, the test-retest reliability of the serious game was found to be considerably higher than the inter-rater reliability of the reference standard, being healthcare professionals using a universal goniometer.

Serious game versus standard care for rehabilitation after distal radius fractures: a protocol for a multicentre randomised controlled trial.

INTRODUCTION: Distal radius fractures are among the most prevalent traumatic injuries worldwide. These injuries are associated with high healthcare-related and socioeconomic costs, mainly resulting from loss of productivity. To optimise recovery and return to work, wrist exercises are recommended. However, adherence to standard exercise regimens is low. Serious games provide a treatment platform for standardised postoperative care, uniting meaningful recovery with entertainment. Also, mobile serious games, for example, smartphone or tablet applications, are able to send practice reminders believed to improve self-efficacy. METHODS AND ANALYSIS: To test the effectiveness of a mobile serious game for distal radius fracture rehabilitation compared with standard care, a multicentre, randomised controlled clinical trial was designed. Primary outcome will be the Patient-Rated Wrist Evaluation (PRWE) score after 6 weeks of treatment. Secondary outcomes are range of motion, grip strength, pain scores, and self-reported treatment adherence after 2, 6 and 12 weeks of treatment.Adult patients with any type of closed distal radius fracture are included directly after non-operative or operative fracture treatment. Patients are recruited in the outpatient clinics of four teaching hospitals. The intended sample size is 92 patients, based on the minimal clinically important difference of the PRWE score at 6 weeks, using a superiority model.Patients are randomised between using the wearable-controlled mobile serious game ReValidate! (intervention group) and standard care consisting of unsupervised exercises and a referral for physiotherapy or exercise therapy upon request or recommendation by the treating clinician (control group). ETHICS AND DISSEMINATION: The protocol has been approved by the Medical Ethical Review Board of the Amsterdam University Medical Centres, location Academic Medical Centre in Amsterdam, the Netherlands. Results will be made available to involved healthcare providers, funders, and to the general public including patients via peer-reviewed academic journals and international conferences. TRIAL REGISTRATION NUMBER: Dutch Trial Registry (NTR), NL6140, protocol V.2.

Healthcare professionals are often unaware of specific rules and regulations regarding the development and use of e-health applications. When does a mobile app qualify as a medical device? What requirements need to be fulfilled before an app can safely be used in patient care? This article provides an overview of important steps in the development of e-health apps. The article describes where to start and which rules and regulations to follow. The provided descriptions are not only important in the development and implementation of corona-apps, but in the use of all e-health apps.

Face Validity and Content Validity of a Game for Distal Radius Fracture Rehabilitation.

Background Patients recovering from a variety of wrist injuries are frequently advised to exercise to regain lost wrist and hand function. Treatment regimens to regain motion in the wrist are highly variable, and adherence to exercise protocols is known to be low. A serious game ReValidate! incorporating standardized exercise regimens was developed to motivate patients. In this study, the game is evaluated regarding its face validity and content validity. Methods In this cross-sectional study, a mixed group of "users" ( n = 53) including patients currently recovering from wrist injury, and a mixed group of "experts" ( n = 46) including professionals advising patients on therapy regimen after wrist injury played at least one complete level of the serious game. Players evaluated the game by means of a structured questionnaire regarding its content, clinical applicability, and user experience. Questions were answered on a Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree). Results All groups valued the game as being able to support wrist rehabilitation and being of use to patients recovering from a distal radius fracture (users: median 4, P25-P75 3-4 vs. experts: median 4, P25-P75 3.50-5; p = not significant). The types of exercises performed during the game were considered to be both realistic and complete compared with regular physiotherapy exercises (users: median 4, P25-P75 3-4 vs. experts: median 4, P25-P75 3-5, p = not significant). Conclusions The ReValidate! serious game can be regarded as a valid tool for patients to regain their wrist function after injury. Level of evidence This is a Level II study.

Establishment of an Early Vascular Network Promotes the Formation of Ectopic Bone.

Vascularization is crucial for the induction of bone formation. In this study, we investigated the application of two subtypes of peripheral blood-derived endothelial progenitor cells (EPCs) to stimulate vessel formation in ectopic bone constructs. Early and late outgrowth EPCs (E-EPC and L-EPC, respectively) were characterized for their ability to form network structures in vitro and perfused vessels subcutaneously in mice. Only L-EPCs showed the formation of fully connected networks on Matrigel two-dimensional (2D) angiogenesis assays. The presence of multipotent stromal cells (MSCs) inhibited network formation in 2D assays, but stimulated network formation in three-dimensional plugs. In vivo studies revealed that at 2 weeks, the highest incidence of formed perfused vessels was reached by implanted E-EPC/MSC constructs and this could be attributed to the presence of E-EPCs. L-EPCs displayed a significantly lower frequency of blood vessel formation than E-EPCs and this was accompanied by a lowering of total luminal area densities. Nevertheless, combined E-EPC/L-EPC application somewhat increased the percentage incidence of perfused vessels. After 6 weeks, differences in vascularization were still obvious as all three EPC-based constructs contained higher numbers of perfused vessels than constructs containing MSCs alone. Bone was formed in all constructs at an incidence that coincided with high density of perfused vessels after 2 weeks. Altogether, our findings suggest the differential establishment of vascular networks by E-EPCs and L-EPCs and suggest the importance of early vasculogenesis in ectopic bone formation.
